4. Installation
2. (continued)
NOTE
All cooling systems are subject to problems from mineral buildup, algae
and bacteria. Frequent changes of coolant and flushing of the system are
necessary to keep any cooling system running efficiently. Frequency of
changes is strictly dependent on the environment and quality of coolant
used. Monitor your cooling system carefully and often.
3. Before mounting the CW on to the M-207A remove the fill cap
and add the coolant mixture. Replace the fill cap. Remove the pins
attached to each corner post (see figure 8). First time installers should
find the CW Power Cable location and find the location of the mating
connector on the bottom of the M-207A.
4. Move the M-207A onto the CW unit and insert the corners onto the posts
of the CW Unit. Carefully tilt the front of the M-207A up slightly. With
the M-207A still slightly tilted connect the CW Power Cable to the mating
connector on the bottom of the M-207A (it is keyed and can only be
inserted one way). Lower the M-207A slowly (feed any excess cable back
into the CW unit). Secure the CW unit with the pins that were removed
(figure 8).
5. Install the adapter cable coolant hoses per section III. Re-connect the M-
207A power cable.
5. Operation -
1. When all connections have been made per Section III and a coolant flow
path is created, turn the M-207A ON and set the CW ON/OFF
switch to ON. The pump should start circulating coolant.
WARNING
DO NOT OPERATE the water cooling unit WITHOUT coolant in the tank
OR WITHOUT a water flow path (water OUT to IN through a weld head).
